BRIDLE-BIT.

SPECIFICATION forming part of Letters Patent No. 354,475, dated December14, I886.

Application filed September 20, 1886. Serial No. 213,992. (No model.) I

' To all whom it may concern:

Be it known that I, GEORGE M. HUBBARD, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inBridle'Bits; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresesent, in

Figure 1, one-half the bit-bar with the loop attached; Fig. 2, avertical central section through the head, showing the loop asintroduced and preparatory to closing; Fig. 3, the same vie-w as Fig. 2,showing the recessed end of loop closed upon the tenon.

This invention relates to an improvement in bridle-bits, in which aringshaped loop'is hinged in the ends of the bit, to which the reins areattached, and particularly to the construction of the loop, whereby itsends are connected through the ends of the bitbar without riveting orsoldering.

A represents the bit-bar, which is constructed with a head, B, at eachend, through which is an opening, a, at right angles to the axis of thebar.

C is a loop of any desired form, preferably of ring shape, and made ofmalleable metal, and is divided, the diameter of the metal at the endsbeing greater than the diameter of the opening a. One end, D, isconstructed with a stud, b, corresponding in diameter to the 0pening ain the end of the bit-bar, so that a shoulder, d, is formed around thestud, which will take a bearing on the head B at one end of the openinga, as seen in Fig. 2. The end of the stud b is reduced to form a tenon,e, enlarged at its outer end. The other end, E, of the loop isconstructed with a recess corresponding in length and diameter to thelength and greatest diameter of the tenon e. The

end E is cast with one or more projections, f, on its outside, distantfrom the extreme end less than the length of the tenon e.

To attach the loop to the bit-bar, pass the studf on the loop throughthe opening a in the head of the bit-bar and close the loop, the tenon centering the recess in the end Eof the loop, as in broken lines, Fig. 2.Then strike or press the projectionsf on the loop inward, which willforce the metal on the inside of the recess into the smaller part of thetenon, as seen in Fig. 3.

I prefer to form the projection f on the outer surface of the end E ofthe loop, as it facilitates the closing of the end of the loop on thetenon. The projection, however, may be omitted and the metal closed uponthetenon by compression. This construction makes a firm pivot-connectionbetween the two ends of the loop through the head, and avoids the use ofrivets, screws, solder, orother device than that which the metal of theloop itself affords.

It will be understood that a like loop is applied to each end of thebit-bar.

This invention is an improvement upon the bridle-bit for which LettersPatent No. 332, .200, were granted me 5 and, I l \Vhat I claim as animprovement, described in said patent, is as follows: j

The combination ofthe bit-bar A, constructed with an opening at each endat right angles to its axis, with a loop at each end, the said loopdivided, one of its ends constructed with a stud to extend through theopening in the end of the bar, and the said stud having a tenonprojecting axially from its'end, said tenon enlarged at its outer end,the other end of the loop constructed with a recess in axial line withthe stud, the said recess being of a diam eter to receive the enlargedend of the stud, and said recessed .end closed upon the tenon,substantially as described.

GEORGE M. HUBBARD.
